POWER WINDOW CONTROL SYSTEM (for Models with Jam Protection Function on 4 Windows) > Key-off Operation Function Operates even if Operating Conditions are not Satisfied


​

DESCRIPTION

  1. When the front doors are closed, each power window regulator motor assembly can control its power window operation for approximately 45 seconds after the ignition switch is turned from ON to off by receiving operation permission signals from the main body ECU (instrument panel J/B).
  2. However, when approximately 45 seconds have elapsed, or the driver side door or front passenger side door is opened within approximately 45 seconds of the ignition switch being turned off, the power window regulator motor assembly stops operating.
  3. During an auto operation, when 45 seconds have passed and key-off operation is prohibited, the window operation will not stop until the auto operation is completed.

INSPECTION PROCEDURE
